I added documentation of various functions that are analogues of traditional locale-dependent functions, but differ in that they allow the caller to explicitly specify a locale. In each case, the documentation was added to the existing page for the traditional functions.

NOTE: There are many more locale-related APIs that remain to be documented (basically following the same pattern as in the above pages), as can be seen in the man-pageslist of of missing pages. Assistance would be very welcome!

The locale(5) page adds documentation of the (GNU-specific) LC_ADDRESS, LC_IDENTIFICATION, LC_MEASUREMENT, LC_NAME, LC_PAPER, and LC_TELEPHONE locale categories. Many other details in this page were also added or improved.
